MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 253,641, dated February14, 1882.

Application filed July 25, 1881.

To all whom it may concern:

Be it known that I,WILLIAM TRABUE, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented new and useful Improvements in Magazine-Guns, ofwhich the following is a specification.

My invention relates to certain new and useful improvements in magazinefire-arms, and IoespecialIy to that class shown and described in LettersPatent No.'238,732, granted to me on:

the 8th day of March, 1881.

My present invention has for its objects to simplify the construction ofthe parts, and more particularly to render the action which is necessaryto secure the proper placement of the shell to be fired absolutelypositive; and with these ends in view myinvention consists in formingthe trigger-guard piece with an incline for directing the rim end orhead of the shell as it leaves the magazine into the bore in the breechof the gun, and combining therewith a breech-bolt provided with alongitudinal finger or extension parallel with the axis 2 5 of the boltand below the bottom surface of the same, so that theforward movement ofthe bolt will cause said finger or projection to travel underneath theshell and lift its forward or bullet end into alignment with the bore ofthe gun before the continued movement of the bolt forces the said shellinto position for firing. By the peculiar construction of the partsnecessary to efiect the automatic introduction of the shells from themagazine into the bore of 3 5 the gun I have endeavored to avoid allpossible liability of derangement, and have therefore sought to secureabsolute positive action. In order that those skilled in the art towhich my invention appertains may fully understand 0 the same, I willproceed to describe the construction and operation,referrin g by lettersto the accompanying drawings, in which- Figure 1 is a verticallongitudinal section through the center of a gun embodying my in- 5vention. Fig. 2 is a side view of the same, showing the breech closedand the trap door to magazine open. Fig. 3is adetail view, showing themethod of opening trap-door by pressure of cartridge; Figs. 4 and 5,detail perspective views of the hammer, and Fig. 6 a

cross-section of bolt and extension.

in the drawings.

Similar letters of reference indicate like parts in the several figures.

A represents the stock of the gun, and B the barrel, arranged in theusual manner, and B is the magazine, with an ordinary springfollower, 0,adapted to force the cartridges or shells one at a time through or alongthe magazine-channel and into the bore in the breech portion of the gun,and in front of the forward end of the bolt. Tliis movement or directionof the shell is effected by means of the incline E, which is formed uponthe trigger-guard piece F, which may be readily cast or forged andplaced in position or removed.

G is the bolt, upon theforward reduced end of which is secured by abayonet-lock or other suitable means a short collar, H,\vhich is formedwith a longitudinal finger or extension, I, that moves back and forth ina suitable guide-slot, while the bolt G, by reason of the manner of itsconnection therewith, is free to make its necessary rotary movements,which are accomplished in the usual manner. This connection between thecollar H and the bolt G is such that the bolt, when entirely withdrawnfrom the gun, may be separated or disconnected from said collar byturning the two parts in an unnatural axial relation and then making alongitudinal movement similar to unlockinga bayonet. From this peculiarconstruction and arrangement of the incline on thetrigger-guard and theextension on the bolt it will be seen that the spring-follower 0, whenthe bolt is drawn back,will force one shell head first into the spaceprepared forit by the rearward movement of the bolt. This cylindricalspace holds the head of the cartridge against any downward movement,while the bullet end of the same is inclined downwardly, as clearly seenNow, as the bolt is forced forward to close the breech of the gun, theextension or finger I travels under the shell and lifts its front endinto proper axial alignment with the bore of the gun, the shell movingon its rim or head as a center or pivot. The shell having now assumedits proper axial position, the continued forward movement of the bolt Gforces the same into its proper place in the breech of the gun and readyto be exploded by the hammer or firing-pin. The movement of the shelljust described, it will be observed,

is accomplished without any spring'or vibratory movement of any of theparts, and hence is absolutely positive in action and not at all liableto any accident or inaction.

J is the hammer of the gun, which is adapted to be forced forward toexplode the shell in any suitable manner.

K is a cam-slot cut in this hammer, and of the form sho\vn,'and intowhich the end of a screw-pin, L, projects. This screw-pin passes throughthe rear end of the bolt G, and the relation of the parts is such, asshown, that the necessary movement of the bolt to open the breech willcause the pin L, by contact with the side of the cam-space, to force thehammer back into a cocked position. movement of the bolt to lock theshell in position moves the pin L into position at the point b, thusleaving the space from b to 0 as a track for the pin when the hammer isreleased to explode the shell.

M is a trap-door on one side, closing an opening to the magazine. Thisdoor is pivoted by an arm, N, at the point d, and a spiral or flatspring, 6, is employed to swing the door into a closed position. At thepoint ofjuncture between the door M and the top edge of the opening intothe magazine the door and frame are cupped or scooped out slightly, andin such manner that the pressure of the conical end of the shell withinsuch cup or hollow will cause the door M to swing downwardly on itspivot d and open the magazine, into which the shell is then introduced,the door M automatically closing thereafter. This door may be opened andkept open by hand until the magazine is com- The forward 4 pletelyloaded, or the shells may be introduced in the manner described.

Recurring to the means for carrying the shell into proper alignment forits subsequent introduction to its seat in the breech of the gun, I maysay that while I have shown the inclines as formed upon or in one piecewith the trigger-guard, I do not wish to confine myself to suchconstruction, as my invention comprehends the broad idea of guides todirect the head or rim end of the shell into position, in

combination with the bolt having a horizontal projection below thebottom of the bore of the gun, and adapted to lift the forward end ofthe shell, as already described. n

It will be observed that, even though the mechanism for transferring theshells from the magazine becomes inoperative, it will in no wise WILLIAMTRABUE. Witnesses:
